|Apr-12-10|| ||JG27Pyth: Nb3# if the b3 square were unguarded. Deflect the guard... I got that far in under 10 seconds... but then became distracted with various back rank ideas trying to attack e1 -- it took a minute to come back to the simple, direct: b3 is guarded once; just deflect the guard and it's over -- this second time around the forcing Qc1+ appeared.|
|Apr-12-10|| ||desiobu: Had already seen this position before, I think on Susan Polgar's blog.|
|Apr-12-10|| ||chrisowen: Trial is missing silken queen check. Ugly defence, the scar you analyze is nick top of the board Qxc1 Nb3 mates the crown. King will look for counsel yet receives none. Star gazing white parks Re1 then takes the bench. It was Qxe3 the bum freezer that wigs him.|
|Apr-12-10|| ||jimmyjimmy: I still have not guessed the correct answer for any puzzle, even on Mondays. I stared at this one for a long while and was positive I was right by simply mating with the knight. I didn't notice white's queen! I have only been on this site for about a month and am a novice even though I have loved chess many years. I just never delved into it enough until now.|

"Examine checks, captures, and threats" is excellent basic advice, but it is generic and does not tailor itself to the demands of a particular position. Although I once followed it, it now only provides a fallback, in case other methods fail. Nowadays, my process is to examine for King mobility and safety first, and then to look for features like burdens, loose pieces, constricted pieces, and pins. The features often suggest a specific course of action, e.g., the constricted Ks today and yesterday demanded examination of the correct candidate.
Just in case my post gave the impression of magically honing in on 30...Qc1+, I also saw 30...Qxf3 as a completely safe move, because of the burdens on the White Qd1. My candidates are the "serious" ones and do not include every move I considered.
|Apr-12-10|| ||kevin86: The key to this one is to set up a mate at b3 by deflecting the queen away from its defense. Other moves offer an alternative move,Qc1+!! does not. THe queen MUST take!|
|Apr-12-10|| ||kingfu: Does 30. Rb4 hold?|
|Apr-12-10|| ||BOSTER: A long, long time ago when <CG> site was great and famous like brilliant chess virtuoso Bobby Fischer, they published the Daily Puzzles.
Here is a brief summary,but not comprehensive description of puzzles' Rules.
<The difficulty of Puzzles increases as the week progresses>.
I guess this is a good reason to call them the weather sensitive (or week sensitive) Puzzles-WSP.
This <CG> site was known not only because some WSP were really tough,not such like Plaskett's puzzle ,nevertheless, and very attractive for many players, but because they had a very strange, old weird custom.
Every Monday, week after week, month after month, year after year they sacrifice the most beautiful woman in chess Kingdom- the Queen.
The Monday's constancy, the monotony had destroyed such natural instinct as the inguisitiveness, and curiosity and as a result the feeling of beauty in chess had been evaporated as a first snow. Monday was known as the Queen sacr. day, and as a result many players played not a chess position, but they played "a day".
Now look like such Monday spirit affected the thinking process of the players.
<zooter>.<It's an easy Monday... Monday means the sacr. of the queen!>.
<stacase>. <Good ol' Monday,good ol'Queen sacrifice>.
<patzer2>. <It's Monday and Qxh3! solves our puzzles>.
<SamAtoms1980>. <That is no ordinary queen you have there on g4. Sacrifice it and the Genle will grant you your wish>.
<kevin86> <Mate ... with queen sacr. Typical Monday>.
<muralman> <What? No queen to sacrifice>
<lost in space > .<I love Mondays!>. Don't skip such Monday puzzle definition : <whitehat>. <There should be a category called "Ridicuiously Easy">.
Certainly not only Monday WSP had the feeling, every day had something special.
Follow <remolino>.<I would offer the exchange in a different way then and try 36...Rd1. Only because it is Sunday. On a Wednesday I would play _36...Rxc3, but on Sunday I play 36...Rd1>.
Today this sounds a little bit strange, but many years ago such innovations were in fashion among <CG> players. But stricktly speaking, who really knows what the correllation exists between "the day of week" and "making the decision in chess" even for OTB games. The raising to SUNday like sunflower a spiral of difficulty WSP attracted many curious visitors as Brazil carnival, but was not able to destroy the Monday expectations.
<Never thought I'd say it but ... thank Goodness it's Monday>.
|Apr-12-10|| ||muralman: These puzzles, over a year of doing them, have helped my understanding of chess theory. |
Monday is suppose to be easy. This Monday puzzle requires at least a modicum of chess savvy.
I looked over the board, and saw two ready players, the knight on C5, and the Queen at E3. The Pawn onA2 makes it all work. Sacrificing the queen wins the checkmate.
The beauty of this attack is how the attacking pieces also strangle the white Queen. It is helpless in fending off the attack.
|Apr-12-10|| ||Major Dude: Pretty Mate. Too easy.|
|Apr-12-10|| ||A Karpov Fan: sweet Monday! :-)|
|Apr-12-10|| ||YouRang: Nice & easy: We have white's immobilized king, and 2 pieces to attack it: (1) Nb3+ and (2) Qc1+ both threats are stopped by white's queen.|
So we use one threat to spring the other! We must start with 30...Qc1+ forcing 31.Qxc1, springing 31...Nb3#.
BTW, we can't start with 30...Nb3?? because after 31.Qxb3, the c1 square remains guarded by the rook.
|Apr-12-10|| ||VincentL: Position "Very easy".
Nb3 would be mate if the white queen wasn't defending b3.
So, deflect the white queen.
30.... Qc1+ does the trick.
After 31. Qxc1 Nb3 mate.
|Apr-12-10|| ||turbo231: It took me about 30 seconds to see it, not bad, not great, just so so. Good thing about it I think it would even work on Rybka. I'm so sure I'm not even going to spend the time it would take to set the position up.|
|Apr-12-10|| ||Kasputin: 30...Qc1+ starts the forced mate combination (to by followed by ...Nb3#).|
|Apr-12-10|| ||Patriot: Thanks, <johnlspouge> for your input. That's a very good thought process to follow. Sometimes the "check, capture, and threat" method becomes daunting when there are a lot of permutations whereas noticing key features such as a stalemated king or loose pieces, etc., cuts to the meat in the position. Jeremy Silman would suggest using his "rules for combinations". Dan Heisman would suggest looking for the "seeds of tactical destruction".|
Also, thanks for your honesty.
|Apr-12-10|| ||tonythekingfisher: Potkin - top ELO rating 2629. Smyslov top rating 2620. Could you really see Smyslov coming up with a lemon like 30 Re1?? In a lost position, he would at least have found Qc2 which staves off imminent calamity at the cost of a pawn.|
Demonstrates the absurd inflation in ratings (over 20 modern players rated higher than Fischer - pull the other one!)
|Apr-12-10|| ||StevieB: Nice easy puzzle, allows for the brain to take it easy once in a while so it doesn't get used up.|
|Apr-12-10|| ||brainzugzwang: <tonythekingfisher: ... Could you really see Smyslov coming up with a lemon like 30 Re1?? In a lost position, he would at least have found Qc2 which staves off imminent calamity at the cost of a pawn.>|
So, how does Black respond if 30. Qc2 is played instead of Re1? Was looking at Rfb8 in an attempt to force Nb3+, but couldn't find anything after 31. b4. Is 30...Qxf3 the best there is?
|Apr-12-10|| ||wals: Rybka 3 1-cpu: 3071mb hash: depth 18:
An evenly paced match until move 26 where White stumbled.
-0.86 Ka1 v Rxd5 0.00.
-(#2) Re1 v Rb4 -0.36
|Apr-12-10|| ||ruzon: I felt that with 17. Qd1 White gave up on his Kingside attack. Why not move it to the g- or h-file to prepare for g6? And I solved the puzzle as easily as most, to those of you keeping track at home.|
|Apr-12-10|| ||Tabanus: I could swear had seen this before somewhere in cg, and indeed:|
Russian Team Championships (2010)
|Apr-12-10|| ||WhiteRook48: 30...Qc1+ how much simpler can you get|
|Apr-12-10|| ||reti: Ingenious and simple.|
